README = '''# Snake

This is a snake game in assembly made for DOSBox and Linux.

You can view the online [Demo](https://donno2048.github.io/snake/) (Use your arrow keys on pc or swipe on mobile).

Inspired by [Can you fit a whole game into a QR code?](https://youtu.be/ExwqNreocpg)

It was made in order to create the smallest "fun" game possible.

To build and run it use:

```sh
sudo apt update
sudo apt install dosbox nasm -y
git clone https://github.com/donno2048/snake
cd snake
nasm snake.asm -o snake.com -f bin
dosbox -c "cycles 1" -c "mount c ." -c "c:" -c "snake"
```

It is so small I could fit it into a single QR:

<img src="./snake.png" width="250"/>

It's `%i` bytes.

open("README.md", "w").write(README % (length // 2, "\n".join(findall('.' * (length // div), hexdata))))
